Mobile usage?
SLIDE 4

Understanding user and context
- Need to work with real
people and real contexts
- User centred design
- Design for dynamic
diversity
- Context centred design
SLIDE 5
www.haptimap.org
Huge difference developer - usage
SLIDE 6
Extreme users and situations
- Creativity – find
new solutions
- Challenge your
design assumptions
SLIDE 7

So, what can you do?
Logging
- Pros: doesn’t interfer with the user experience
- Cons: hard to interpret, large amounts of data
– We have used it mainly to support qualitative
- bservations (so far)
SLIDE 8
www.haptimap.org
Semi-controlled outdoor tests
- Pros: more
realistic, faster, can focus on one part
- Cons: how realistic
is it? Cannot control everything (eg GPS). Hard to
- bserve when
walking behind
SLIDE 9
www.haptimap.org
More or less controlled
SLIDE 10

Real time Lo-Fi WOZ
- Pros: easy to do
- Cons: a person is not a
mobile device…depends a lot on the wizard/oracle (prepare carefully!). Also – important not to disturb by recording.
SLIDE 11

Simulations
- Pros: Help to analyze, can vary
parameters freely. Can run LARGE number of tests.
- Cons: ”Did we implement it
right?” (can also get very complicated if one starts getting elaborate).
SLIDE 12

Interviews (sitting down)
- Standard
- Often semi
structured
SLIDE 13
www.haptimap.org
Inteviews in mobile context
- You get different comments/answers if you do
the interview in context!
SLIDE 14
www.haptimap.org
Interview tip
- Festivals, carnivals (where large numbers of
people queue or wait for things can be very useful – you can do a lot in just a few hours!
SLIDE 15
www.haptimap.org
Focus groups
- Semi-structured
- Thought
support/priming important
- Documentation?
- How well do people
remember…do they do what they say?
- Go outside too!
SLIDE 16
www.haptimap.org
User workshops
- With demonstration
- walk. Can get new
perspectives compared to ordinary interviews.
- Users are not designers.
Need moderator.
SLIDE 17
www.haptimap.org
Diaries /probes
- Good, long term
- info. Don’t have to
be there.
- Tiring? Response
rate…..
SLIDE 18
www.haptimap.org
Video
- bservations
Visual interfaces often make you stop. Reading and texting while walking is hard. Reading and texting while cycling is dangerous.
SLIDE 19
www.haptimap.org
Simulated use in the wild
- Lo-fi paper overlays. Weather a problem. Hard to
know what information the user really receives.
SLIDE 20
www.haptimap.org
Discussion/conclusion
- Need a toolbox of methods
– How to observe when walking behind? – It isn’t possible to carry out tests in all weather types – You cant expect people to walk very far, especially not when you are working with elderly persons or persons with mobility problems – You need to find safe test environments for persons with visual impairments – People have different walking speeds
SLIDE 21
www.haptimap.org
Discussion/conclusion
- Hard to observe audio in headphones or
vibrations
- Simulations can be a useful complement
- Examples/though support important – need to
explore the design space with the users
SLIDE 22
What do you want?
What can I get?
SLIDE 23
Need a toolbox!
